Can I get highlighted text with JQuery?
提问by Mr. Lavalamp
I'm not finding anything anywhere. Is there a JQuery solution to retrieve highlighted text? I need to check the highlighted text for spans, get those spans' style attributes, and manipulate them based on that. I can do that part with regular expressions or whatever obviously, but first I need access to the highlighted text! I'm struggling to even find a cross-browser plain javascript solution, so if you've got one of those handy that would help immensely as well.
我在任何地方都找不到任何东西。是否有 JQuery 解决方案来检索突出显示的文本？我需要检查突出显示的跨度文本，获取这些跨度的样式属性，并基于此操作它们。我可以用正则表达式或其他明显的东西来做那部分，但首先我需要访问突出显示的文本！我什至很难找到一个跨浏览器的纯 javascript 解决方案，所以如果你有一个方便的解决方案，那也会有很大帮助。
Thanks!
谢谢！

You mean text selection with mouse, so check here, DEMO http://jsfiddle.net/yeyene/GYuBv/2/
你的意思是用鼠标选择文本，所以在这里检查，DEMO http://jsfiddle.net/yeyene/GYuBv/2/
$('#showSelected').on('click', function(){
var text = "";
if (window.getSelection) {
text = window.getSelection().toString();
} else if (document.selection && document.selection.type != "Control") {
text = document.selection.createRange().text;
}
alert(text);
});
If you want to do some changes around selected text, check this DEMO http://jsfiddle.net/yeyene/GYuBv/3/
